20 Claims.

The present invention relates to tools and more in particular to rollerbearing cup removing tools.

Among the objects of the present invention is to provide a novel tooladapted to be used in conjunction with suitable power means for removingroller bearing cups pressed within the housing of car wheel axles.

Another object of the invention is to provide a novel tool which maybereadily and easily inserted Within the housing of car axles and havingmeans adapted to engage with a roller bearing cup for removal of thesame from the housing.

The invention comprehends the idea of providing a novel roller bearingcup removing tool adapted to be easily inserted into the housing for acar wheel and having means, such as movable elements controlled bysuitable means, for moving these elements into a position for engagementwith the roller bearing cup. y

A still further object of the present invention is to provide a noveltool having means for locking these movable elements against outwardmovement, whereby the same are held in a position to provide clearancefor insertion of said tool within a roller bearing cup in the housing ofa car axle.

Still another object of the present invention is to provide a novelroller bearing cup removing tool having relatively movable tool membersadapted to be clamped in engaging relation with cup pushing elementsinterposed therebetween and for holding these elements in position forengagement with the roller bearing cup, suitable means being providedfor applying pressure to the tool for removing the roller bearing cupfrom the housing of the car axle.

The invention further contemplates the idea of providing a roller cupremoving tool in which the cup pushing elements are guided by one of therelatively movable members of the tool and moved outwardly by means,such as a cam surface provided on the other of the movable members, intoa position for engagement with the roller bearing cup. Further means,such as lock elements, are provided on the last mentioned member forlocking said elements to provide clearance for insertion of said toolVwithin said roller bearing cup.

With these and various-other objects in view, the invention may consistof certain novel features of construction and operation as will be morefully described and particularly pointed out in the specification,drawing and claims appended hereto.

In the drawing which illustratesV an embodiment of the device, andwherein like reference characters are used to designate like parts-Figure 1 is a fragmentary View in side elevation of a wheel press, anembodiment of the present invention being disclosed in cross section inassociation with an axle housing supported in the wheel press;

Figure 2'is a View in cross section of an embodiment of the presentinvention; and

Figure 3 is a View in front elevation of the embodiment disclosed inFigure 2 oi the drawing.

Referring now more in detail to the drawing, an embodiment selected toillustrate the present invention is shown as comprising an inner movablemember 2, an outer movable member 4, and roller P bearing cup pushingplates 6, 8 and 10 interposed between these two movable members. Themovable member 2 comprises a disc shaped backing plate 12 having anoutwardly extending shaft 14 integral therewith and provided with alaterally extending rod 16 having an end fitting `within a bore ordrilled opening adjacent the outer end of the shaft 14.v

The outer movable member 4 comprises a plate element or part 18 havingan integrally and outwardly extending tubular hub or shaft 20 adapted tot over and encircle the shaft 14 of the inner member 2. This shaft orhub 20 is provided with an integrally and laterally extending handle 22.The backing plate or portion l2 is provided with elongated and radiallyextending slots or openings 24 adapted to receive projecting dowels 26and 28 fitting in each of the roller bearing cup pushing plates orelements and for guiding these plates or elements between the backingpart 12 and plate '4 element 18 of the inner and outer tool members 2and 4, respectively.

The shaft 14 is provided with a transverse slot 30 adapted toreceive akey 32 passing downwardly through aligned openings 34 and 36 provided inthe walls of the tubular hub 20, this key 32 being adapted to be forcedinto engagement with a wall of the slot 30 and the ends of the openings34 and 36 for clamping the inner and outer movable members in contactingengagement with the roller bearing cup pushing plates or elements 6, 8and l0.

As clearly shown in Figure 3 of the drawing, the plateelement 18 of theouter movable member 4 is provided with cam surfaces 38, 40 and 42adapted to engage with cam follower portions 44 of the pins or doWels26, projecting from the iront face of the roller bearing cup pushingplates. Each of these cam surfaces terminates in a locking element 46overhanging the adjacent cam surface and in spaced relation therewith toprovide slots or openings 48.

As shown in Figures 2 and 3 of the drawing, the cam followers 44 of theroller bearing cup pushing plates are in engagement with these camsurfaces adjacent the locking elements 46, these plates being maintainedin this position by the clamping action of the key 32 passing throughthe hub 2G and shaft 14 of the outer and inner movable members,respectively. The position of the plates under these conditions is suchas to cause the same to engage the rear surface of the roller bearingcup 50 fitting within the axle housing 52, which in turn is positionedbetween wood blocking 54 of a bolster of a wheel press 56. The backingplate part or portion 12 of the inner movable member 2 is engaged by theend -of a Wrought iron pipe 58, or other means, of a press ram 60 forapplying a pressure or force to the inner member 2 and for forcing theroller bearing cup 50 from the axle housing.

The roller bearing cup removing tool may be removed from the rollerbearing cup by removing the key and rotating the handle 22 in acounterclockwise position so that the cam follower 44 of the plate 6drops onto the cam surface 40, it being necessary to manually move theplates 8 and 10 into a similar position with the cam surfaces 42 and 38.respectively. f

The handle 22 maythcn be moved in a clockwise position, as viewed inFigure 3 of the drawing, whereby the cam followers 44 enter into theslots 48 and are locked in position by the locking elements 46. Thismovement of the plates 6, 8 and 10 provides sunicient clearance forremoving the tool from the roller bearing cup, as likewise to positionthese plates whereby the tool may be easily and readily inserted withinthe roller bearing cup at the other end of the axle housing, or inanother axle housing.

It is to be understood that I donot wish to be limited by the exactembodiment of the device shown, which is merely by way of illustrationand not limitation, as various and other forms of the device will ofcourse beapparent to those skilled in the art without departing from thespirit of the invention or the scope of the claims.
